Floribunda rose plant named `Devsmooth`

ABSTRACT

A floribunda rose variety producing red flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct floribunda rose variety which was originated by our crossing as seed parent the variety known as `Sassy` (U.S. Plant Pat. No. 4,559) and as pollen parent an unnamed seedling (70270-2). The varietal denomination of this new rose is `Devsmooth`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by the new variety which distinguish it from its parents and all other varieties of which we are aware are its attractive, bright red flowers with long stems borne with few thorns on a bushy, vigorous plant.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction for roses may be also employed.

COMPARISON WITH PARENT

The new variety differs from `Sassy` in flower size and color.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying illustration show typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
